intel-iommu: Fix reattaching of devices to identity mapping domain
When we reattach a device to the si_domain (because it's been removed from a VM), we weren't calling domain_context_mapping() to actually tell the hardware about that. We should really put the call to domain_context_mapping() into domain_add_dev_info() -- we never call the latter without also doing the former, and we can keep the error paths simple that way. But that's a cleanup which can wait for 2.6.32 now. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
